l To all whom it may concern:

Be it known that I, JOSEPH MARX, citizenv of the United States, residing at Bufalo, in

have invented certain new and useful Im- 'provements in Jars for Storage Batterles, of

' which the following is a specification.

lao

The present invention contemplates certain new and .useful improvements' inthe construction of jars for storage batteries and the like, and aims to provide a novel jar of this character which is peculiarly formed so as to effectively retain the acid and prevent 'it from 'coming into contact with the metallic portions of the jar.

The ob 'ect of the invention is to provide a jar for storage batteries which is of sim le and durable construction and can be rea ily transportedfrom place to place.

For a full description of the invention and the merits thereof and also -to acquire a knowledge of the details of constructionand the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which :f

Figure 1 is a perspective viewof a jar embodying the-invention, portions being broken away. Fig. 2 is a. longitudinal sectional view throughA the jar. Fig. 3 is a transverse sectional view through the same.

Corresponding andlike parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In its broadest phase the inventioncomprises a jar formed with an inner sliell of hardrubber or othersimilar material ada ted to resist the action of the acid within t e battery, and an outer metallic shell designed to receive the inner shell and form a protective casing for the same.

The outer shell indicated at 1 may be rovided with the outwardl pressedrein orcing ribs 2y and has a hand e 3 applied thereto by means of which the battery can be readily carried from place to place. In the present instance this handle 3 is inthe nature of a leather stra the ends of which detachably sides of the jar. The inner shell 5.its closely Within the outer shell 1 and extends upwardly above the same, the outer edge of t e inner shell being formed with an annular enlargelment or rim` 6 which'renforces the mouth of the shell and carries a downwardly extending lip 7 fitting over and embracing the edge ofthe outer shell l. In the present instance this lip 7 is shown as formed of some yielding material such as soft rubber which is vulcanized to the rim'. This manner of. forming the lip has the Iadvantage of enabling the same to yield and accommodate itself tol slight changes of shape in the outer shell 1 and 4at the same time always producing a close joint between the two members which effectively prevents lany acid from working between the same. The inner shell 5 is s'ubdivided into a plurality of compartments by the partitions l8 and transversely disposedV in an elevated position and prevent the same fromresting upon the bottom'of the jar. It will be readily apparent ,that with -a jar thus'. constructed the acid will be prevented. from getting inside of the metal case and will not act upon the edge of the jar since the latter is constituted by the annular rim 6.

Having thus described the invention, what is claimed as new is:

In a jar for stora e batteries, the combination of an outer she l, an inner shell formed of hard rubber and ttin Within vthe outer shell, the said inner shel being rovided at its mouth with an enlarged annu ar rim also formed of hard rubber and extending over and resting upon the edge of the outer shell, and a lip of soft rubber pendent from the enlarged rimand overlapping the edge vof the outer shell upon the exterior thereof.

In.testimoll1y whereof I aIix my signature in presence .of twowitnesses.
